I still can't use the program properly for the mac though. I downloaded the demo from the official website (again) and the library isn't empty, I can actually see the noises and patterns. Could you please look in to this? Cause I would love to use the program on the mac as well, but so far I haven't had any luck with trying to get it to work, at all.

No it didn't. After reinstalling it again I did see the items in the library but they all looked like big red crosses, maybe indicating the library items can't be found? The resources folder, was initially empty apart from the view3d folder, so I copied the other folders from the Windows version.I think it was kind of weird that the resources folder was so empty though. But manually copying and pasting didn't do the trick.

Everything else works, the program just can't find or recognize or find the library items?
